SOURCE: Leaking Heater core

not much more you can do but replace the heater core

do NOT use stop leak... it may stop the leak but it will plug up the heater core and other small passages needed for cooling the motor as well.

I have a 1991 buick regal and when i turn the heat on only cool air blows out. it doesnt leak on floor either as if heater core was out. what should i do


Check that the heater core is not plugged by feeling the 2 heater hoses going into the firewall. If they both get hot, then the heater core is not at fault.

If they are cool, then the heater core is plugged then the heater core will have to be replaced.
